Search for squarks and gluinos with the ATLAS detector using final states with jets and missing transverse momentum and 5.8 fb$^{-1}$ of $\sqrt{s}$=8 TeV proton-proton collision data

A search for squarks and gluinos in final states containing jets, missing transverse momentum and no high-pt electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in $\sqrt{s}$=8 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated lumi...

description A search for squarks and gluinos in final states containing jets, missing transverse momentum and no high-pt electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in $\sqrt{s}$=8 TeV proton-proton collisions at the Large Hadron Collider, with a total integrated luminosity of 5.8 fb$^{-1}$. No excess above the Standard Model background expectation is observed. Gluino masses below 1100 GeV, and squark masses below 630 GeV are excluded at the 95% confidence level in simplified models containing only squarks of the first two generations, a gluino octet and a massless neutralino. In mSUGRA/CMSSM models with tan$\beta$=10, $A_0$=0 and $\mu>$0, squarks and gluinos of equal mass are excluded for masses below 1500 GeV. These limits extend the region of supersymmetric parameter space excluded by previous measurements with the ATLAS detector.
